To all whom it may concern: 1

Be it-known that 1, CHARLES a citizen of the United States, of Eastomin the county of and State of- Pennsylvania, new and useful specification.

mounting in which the drill may be moved to one side to bring the drill out of alinement with the hole-being bored for permitting the shifting of the drill steels as the hole becomes deeper.

The object of this invention is. to pro.- vide novel ,means which may be operated for quickly locking the clamp to and releasing it from its support; for locking the saddle to and releasing it from the clamp and for locking the drill shell to and releasing it from the saddle.

A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 represents the mounting in top plan, a portion of its supporting arm being shown in side elevation, Fig. 2 is a side view of the mounting, the supporting arm being shown in transverse section and the drill and Fig. 5 isa view The column arm which is hereinshown as,

forming the support for the mounting is denoted by 1. The clamp which embraces this arm comprises two members 2, 3, hinged at 4 and their free ends engaged by a bolt 5, the cross head 6 of which is seated in the clamp member and the nut 7 of which is enaged with the screw threaded end of the bolt beyond the clamp member 3.

The means which I have shown for securing an instantaneous locking and releasing of the clamp comprises a wedge key 8 interposed between the nut 7 and clamp member 3. j

A washer 9 is preferably inserted between i the nut 7 and (LHANSEN, and resident Northampton have inventedj Improvements Drill- Mountings, of which the following "is a" I stop of Fig. 2, looking in the of the wedge keyused for key 8 is-providedwith an elongated slot 10 through'whichthe bolt 5 passes."

The clamp member2 is provided with parallelbevel guides 11 12, on which the saddle 13 is 'slidably -mounted. The flat member 2 is further provided with a fixed 14 for limiting the sliding movement of, the saddle in oner direction along the clamp andithe clamp member is further providedwith aremovable "stop 15, in the present instance a bolt for limiting the sliding movement of the saddle in the opposite direction. 1 This bolt 15-may be unscrewed "at any time to permit the insertion and removal of the saddle. a The saddle .-l3 .is

beveled wedge key 16, the beveled parallel side 17 of which engages the bevel guide 12 of the clamp member 2 and the tapered side 18 of which engages the tapered walls of the saddle 13. This wedge key 16 is'provided with a head 19 at its smaller end for preventing the complete removal of thegwedge key when in its released position.

' The cone 20 of the drill shell is seated upon the saddle 13 and is engaged by a stationary jaw 21 and movablejaw 22. This drill shell cone 20 is locked to and released from the saddle has its head 24; seated within the saddle 13, which bolt passes through the movable jaw 22 and is provided with a nut 25 on its screw threaded end exterior to said jaw. A wedge key 26, is interposed between the outer face of the movable jaw 22 and the nut 25, which .key is provided with an elongated slot 27 throu h whichthe bolt 23 passes. A washer 28 is preferably inserted between the wedge key-26 and the nut 25.

In operation, locked to the arm 1 by a blow upon the large end of the wedge key 8 after the clamp has been adjusted to the proper position on the said arm. The saddle 13 with its drill may then be moved to either limit of its movement and there locked to the clamp by a blow upon thelarge end of the wedge key 16. The drill may be adjusted rotatively to the proper position with respect to the saddle and then looked in such position by large end of the wedge key hole has been drilled to a the use of a longer a blow upon the 26. After the depth sufficient to require the wedge kyiS. This wedge looked to and released from the clamp member 2 by means of a 13 as follows :-A bolt 23 the slidearm clamp is first" 3 if clamp a sufficient distanceto bring the drill loclnng the saddle-to and releasing it from;

drill steel, thedrill may be Withdrawn 011 its arm support and for looking the drill shell to and releasing it from the saddle.

What I claim is 1. In a drill mounting, a clamp, a saddle slidable thereon and a longitudinally slidable Wedge key interposed between portions ofthe clamp and saddle for instantaneously lockingthe saddle to and releasing it from the clamp.

2. In a drill mounting, a clamp having parallel guides thereon, a saddle fitted to slide along the guides and a Wedge key interposed between the saddle and one of the guides and slidable in the direction of the gui es for instantaneously locking the saddie to and releasing it from the clamp.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two witnesses, this 5th day of January, 1910.

its shell sufliclently to release the drill steel there rom. Ablow upontlre'small-end of the Wedge 'lrey1"6 'Will immediately release the saddle from the saddle clamp. The saddle and drill may then be moved along "the out-of 'alin-"ement With the 'hole being bored thus permitting the removal of the shorter. steel and the insertion of a longer steel. The saddle, With the-drill, may then be moved back to its original position and after, the drill has been engaged withits drill steel and the saddle locked to; the clamp, the op-J eration of the drill maybe proceeded With.

"From the above description it will be seen that no adjustment-oithe drillis required each time a new steel isusedand it Will be furthermore seen *that a very-simple and; quicklyoperated device is employed for CHARLES C. HANSEN.
